Kodokan Randori and IJF Rules

Can anyone elaborate on how the IJF ruleset's standardization in Japanese tournaments impacts Kodokan training? I had the understanding that the Kodokan was distinct from the IJF and could be one of the few places Judo could actually be studied and practiced to its full extent, but searching around apparently they train for IJF rules now?

The Kodokan is a private dojo and isn't even bound by the AJJF. It can have whatever rules it wants for its internal tournaments.

I don't know what effect if any the IJF rules have had on training there, but I would imagine leg grabs weren't a big part of training before the rule changes so the impact would have been minimal at most.

There was a lag time before they adopted the no leg attacks rule for their internal competitions, I remember reading, but they have done so now.
